Time traveller here we go?

2007-03-12T23:06:36Z

Here is a simple copy of a brief article i found on the net talking about time travel. As a physic geek i took a look at it and made a few more research online to figure out if it is a good article or just mix of fake things. Guess what, that's a serious point. Althought I got a master degree in physic sciences I was not able to understand everything I found online on this topic (I mean I did not take time to analyze every theory under that topic and every math things) but it seems to be just "right" even if not feasible right now ;)
So, after teleportation at the speed of light (realistic transportation system, no kidding) time travel becomes an option even to the past (kind reminder that Einstein basic theory suggest (or demonstrate, it's up to you) that time travel in the future is possible). It could turn to a way to travel after the disparition of planes because of a lack of gas ;) oups i forgot, it need more than the energy or a star to work (in theory). see the article =>

The urge to hug a departed loved one again or prevent atrocities are among the compelling reasons that keep the notion of time travel alive in the minds of many.

While the idea makes for great fiction, some scientists now say traveling to the past is impossible.

There are a handful of scenarios that theorists have suggested for how one might travel to the past, said Brian Greene, author of the bestseller, “The Elegant Universe” and a physicist at Columbia University.“And almost all of them, if you look at them closely, brush up right at the edge of physics as we understand it. Most of us think that almost all of them can be ruled out.”

The fourth dimension
In physics, time is described as a dimension much like length, width, and height. When you travel from your house to the grocery store, you’re traveling through a direction in space, making headway in all the spatial dimensions — length, width and height. But you’re also traveling forward in time, the fourth dimension.

“Space and time are tangled together in a sort of a four-dimensional fabric called space-time,” said Charles Liu, an astrophysicist with the City University of New York, College of Staten Island and co-author of the book “One Universe: At Home In The Cosmos.”

Space-time, Liu explains, can be thought of as a piece of spandex with four dimensions. “When something that has mass—you and I, an object, a planet, or any star — sits in that piece of four-dimensional spandex, it causes it to create a dimple,” he said. “That dimple is a manifestation of space-time bending to accommodate this mass.”

The bending of space-time causes objects to move on a curved path and that curvature of space is what we know as gravity.

Mathematically one can go backwards or forwards in the three spatial dimensions. But time doesn’t share this multi-directional freedom.

“In this four-dimensional space-time, you’re only able to move forward in time,” Liu told LiveScience.

Tunneling to the past
A handful of proposals exist for time travel. The most developed of these approaches involves a wormhole—a hypothetical tunnel connecting two regions of space-time. The regions bridged could be two completely different universes or two parts of one universe. Matter can travel through either mouth of the wormhole to reach a destination on the other side.

“Wormholes are the future, wormholes are the past,” said Michio Kaku, author of “Hyperspace” and “Parallel Worlds” and a physicist at the City University of New York. “But we have to be very careful. The gasoline necessary to energize a time machine is far beyond anything that we can assemble with today’s technology.”

To punch a hole into the fabric of space-time, Kaku explained, would require the energy of a star or negative energy, an exotic entity with an energy of less than nothing.

Greene, an expert on string theory—which views matter in a minimum of 10 dimensions and tries to bridge the gap between particle physics and nature's fundamental forces, questioned this scenario.

“Many people who study the subject doubt that that approach has any chance of working,” Greene said in an interview . “But the basic idea if you’re very, very optimistic is that if you fiddle with the wormhole openings, you can make it not only a shortcut from a point in space to another point in space, but a shortcut from one moment in time to another moment in time.

Cosmic strings
Another popular theory for potential time travelers involves something called cosmic strings —narrow tubes of energy stretched across the entire length of the ever-expanding universe. These skinny regions, leftover from the early cosmos, are predicted to contain huge amounts of mass and therefore could warp the space-time around them.

Cosmic strings are either infinite or they’re in loops, with no ends, said J. Richard Gott, author of “Time Travel in Einstein's Universe” and an astrophysicist at Princeton University. “So they are either like spaghetti or SpaghettiO’s.”

The approach of two such strings parallel to each other, said Gott, will bend space-time so vigorously and in such a particular configuration that might make time travel possible, in theory.

“This is a project that a super civilization might attempt,” Gott told LiveScience. “It’s far beyond what we can do. We’re a civilization that’s not even controlling the energy resources of our planet.”

601 Movie Team 7 production

2006-12-11T15:23:41Z

Here is the scenario...

]]> First, the way to cics from home to cics with a focus on the tower, then CICS building and step in the hall
(the initial was to have a walk till a class room and have Dr gillette "a bas le roi!" video)
The previous scene with a heartbeat sound to involve part of stress and intense feeling we felt the first time
Then introduction of the CICS Logo and opening the CICS portfolio with the shared values of cics in it.
Switching to godfather music and the pronounciation of values of the CICS by professors and staff, initialy we wanted to have everybody but because of time issue we didn't manage to do that. The first idea was also to turned it to black and white sequence but we (in fact I for this point)... forgot to do it :(
Then we wanted to introduce the labs and hands on teaching part of cics, to make it funny we move in labs with the mc gyver soundtrack.
On a third part team work, meetings, presentation and celebration as a common sequence of work to present our real day by day experience. with some good piece of the accenture challenge which is a perfect example.
Next point was about introducing the social learning program, the issue was that we didn't have movie for this part so we had to work with pictures. and a couple of sequence about amazing things of this year.
Then by closing the CICS portfolio we close the story....hum...no a last point is a stolen sequence of the accenture challenge night to illustratr the "play hard" topic ;)
Ths movie will be available on mu ilocker in a couple of days (after finals)

Communication flow renaissance

2006-12-11T14:39:37Z

For the last 100 years many field have evolved but one of them, thanks to technology, have known a real revolution… a renaissance.
The communication flow between people for personal or professional reasons is getting faster and easier day by day.

]]> Till 1876 (patent for phones by A G Bell) communication between people was only verbal when you were talking to someone or via mails. These two methods involved delay as you need to find the person to talk or to wait for the mail to arrive to the receiver.
Communication started changing with the invention of phones. This device allowed people to reach someone in a short time and talk with this person…if he or she was home. It was to first step to make the communication faster and easier.
However official papers still had to be sent by mail and needed time.
One step further was to make international connections for phone calls.
A long time after this invention (in th 90s’) appeared the internet, and the “e-mail” till this time people were able to reach someone quickly not only to talk but to send written information, it also allowed people to hae a track of what they said or not (it became a very strategic fact in companies). However, because a lack of security and legal rules people couldn’t make any official written decision by e-mail, paper and signature were still needed.
A little time later appeared the need of mobility (especially for business men) the phone moved to mobile phone, allowing people to be reached anytime anywhere this technology quickly involved everybody and not only business men.
In the same time the security and technology for the internet allowed to provide services to insure total security for signature of official papers in e-mail, this is also a great step in making communication flow easier especially for companies, however we can highlight that some countries still have a lack of law for official paper over e-mail.
Lately (about 2 years ago), data transmission and so access to internet and e-mail came on the mobile field with built in browser in cell phones and PCMCIA cards for computer to connect them to wireless access. Now you can even sign your new contract in a train, or also access to every kind of information (video, sounds etc…) when you are walking in the street.
A last point during the last 10 years is the invention of instant messaging, when you need to talk to someone but cannot reach him on the phone for any reason you can leave him an instant message (or maybe you need a track of this informal message) if he/she is online and he/she will see the message as soon as he/she is on the computer. You can also make live chat using this instant messenger, sometimes it can be an easier way to talk with someone who doesn’t speak your language (writing is usually easier than speaking), and with these writing message you can also include emoticon to involve a feeling with you sentence. Lately instant messengers turned mobile to and can be on your cell phones.
An thanks to UMTS, we can now even see the person we are calling like on a webcam…
Getting closer to star trek… we still need to find a way for instant transportation.

Leonardo da vinci

2006-12-11T04:09:03Z

In my point of view leonardo da vinci is the most representative character of the renaissance. The renaissance involved several field (as explained in a previous blog) and leonardo da vinci made important things in each of the fields involved by the renaissance. He is the most complete "renaissance superman" in my opinion.

]]> Leonardo is the fruit of an illegal relationship between his Ser piero da vinci and the daughter of a farmer from toscane, catarina.
His inital education is painting (topic where he was an outstanding student) but even if leonardo invented several new technical solution for this field and made many great paintings he also worked i other fields.
As an engineer he invented solutions to improve clock, weaving loom... he studied also town planning and proposed plans of ideal cities and made several papers with vision of potential future machines like plane, tank etc... .
As biologist he spent time analyzing natural enigma like how birds fly.
About medecine his paper "the vitruvian man" is the first about scientific vision of the human anatomy.
About literacy, he wrote for example the codex of turin, but also several notes with more philosophical content.
Leonard was also sculptor.
This human being was the perfect fusion of a scientist, a philosopher and artist... the perfect image of human renaissance isn't it?

The wii iissue

2006-12-11T03:53:57Z

I just want to blog on a funny issue that some of you have probably heard...about nintendo

]]> As you all know, nintendo started to sale few weeks ago a new video game system called the "wii". Till the recent wii, nintendo had been kind of absent of the market of video games hardware (except mobile devices). This new system include a totally new and amazing control pad that allow you to control the game by moving like you would do it in real (like when you play tennis for example).
According to some games full of action (like sports game) and some times the need to launch the control pad, nintendo built a system of cable and lace (linked to the player) to keep the control pad safe of any contact with the ground that could break it.
Funny point is that this week they discovered that people are that much involved and interact with the video game that sometimes maybe they forget that it is a control pad and use it like a real sport device, smatching with big strengh and sometimes when the control get out of their hands the cable break and the control pad fly away...
and so breaking the control pad.
Maybe we could think that it is an easy way for nintendo to sale move control pad or that it was in fact an engineering mistake. However the customers didn't change their minds and are still rushing day by day in stores when they receive new "wii" for sale.

This is not techno

2006-12-11T03:35:41Z

Ok here we go. Thanks to many american people i feel like i have to provide some definition about the kind of music i mix as a DeeJay (Josh i think you are the only one who don't need to read it).

]]> House music is of course an electo music (it means essentially made thanks to electronic) and it is a common point with techno. But except this point, techno and house are i would say totally different (even if some flavour of house like hard-house could be closer to techno but we will focus on the "initial" house music).
First of all even if you could think the opposite, House music find its initial inspiration in... Disco, when techno music is essentially about big beat and not that much melody and without real sources of inspiration.
Then i would say that House is usually slower than techno, usual house music is between 120 to 130 BPM (Beat Per Minute) when house usually start at 135BPM.
An other pointis that House music usually involve lyrics when techno usually doesn't have any (whe can also figure out that most of House music lyrics are about "happy" topics like love, oarty etc. and are made to make people dance).
On a more "musical" point, the bass beat in house music is only usually to indicate the rythm when it is a big part of a techno music composition, i like to say that if you cut the bass on a techno music the music you will hear won't make sense neither feelings but if you cut the bass on a House music it will still sounds like a music (even if it could loose a part of its power).
Explaining by example, try: Floorfilla "anthem 4" (Techno) and compare to Bob sinclar "Feel for you" (house music)
and you will understand that this is not techno!!!!!!!!!!!!!!

Outsourcing definition

2006-12-10T18:36:54Z

Outsourcing is part of new strategies in companies. The purpose of outsourcing is to allow the company to focus on its core work without having to deal with other activities (for example IT oursorcing could be helpful for company like saint gobain which is a can and bottle manufacturer).

]]> Outsorcing non strategic components is usually the best way to increase the level of these component and reducing their cost at the same time.
However it's important to notice that a company should not outsource critical components of its work because it could be risky because your process could be use for your competitors (by the outsourcing company) and also your comapny is loosing values in terms of knowledge. A company should not outsource the part of its work that make their money.
Outsourcing is also a way to increase flexibility of a company, the outsourcing company usually take care to adapt the outsourced service to the new needs of company, this way it increase their flexibility.
An important point in outsourcing is the relationship between the company and the outsourcing company and also the control and dependance they have one to an other.
In opposition to all these principles we can show the example of Sprint that started its complete business with consultant...which is basically outsourcing the complete company.
Is it fair compared to other comapnies that built their network with their own team, i don't know, but does business care about fairness, and so far this company is doing pretty good. Let's see if we can apply it in class ;)

information renaissance

2006-12-10T16:14:26Z

comparing the 20th and 21st century to the15th and 16th century we can consider that we have lived, and are still living a renaissance of information and communication according to the number of innovation. We went from newspaper to tv news over satelite or internet, from mail to email, from telegraph to cell phones. All these technologywere not even in any thoughts in the last century, however it happened.

]]> We live a time where new technology appear every day, it can be compared to the same technical evolution that happened during the renaissance like printing, or in architecture (don't we build new architecture for network, new architecture for organizations also). The content has evolved too, going from personnal mail written on simple paper to multimedia messages including files, video. In term of content we can also talk about the evolution of news and papers content, going from very political or scientific to more common with magazine oriented to special customers (young,hobbies etc...). In some ways the writing changed, like for sms or email including shorten word to reduce the needed space and include more content in a 160 character message or adding some visual effects like smileys to add an emotion (who said emoticon) to message involving non writing communication in a writing message, that is also a part of information and communication renaissance.
To conclude we can admit that every segment of information and communication are living a renaissance and changed our society thanks to technical evolution, content evolution, and changes abiut human communication, using new flows and new vision of how it should be.

Renaissance prelude

2006-12-10T01:50:59Z

Renaissance is a period of literary, artistic, and scientific restoration that happened in Europe during the XV and XVI century.
This movement started in italy with a “pre-renaissance” in the late XIV century, and grow in term of propagation till the complete europe in the XVI century.

]]> During XV and XVI century, “Renaissance” involved many travels trough seas (who said 1492 ?). Renaissance also involved many changes in the religion but overall it provided to Europe every things it needed to overpass Arabic countries and china on a technical and cultural point of view.
According to John Hale (historian), it is during the renaissance that the word Europe jumped into the language and mentioned on official maps, affirming its visual and cultural identity.
The “renaissance” period is a very important part of history, making the connection between the medieval and modern times.
This period of time saw the modification of the world map including USA (thanks to christophe colomb) and the Europe on official maps. Technical improvements like printing (Gutember 1453), new painting techniques and famous painting (“clair obscur” used by Leonardo da vinci painting “la joconde”), many architectural improvement and new constructions (“palais des papes” in avignon)
Renaissance can be shown like a revolution in the world by this time.

My theory of human communication

2006-12-10T00:59:03Z

(part of collaborating work)
According to Stephen W. Littlejohn (2002,p3) “communication is one of the most pervasive, important, and complex aspect of human life”. Discoursing about my theory of human communication, I will first define and describe human communication, then discuss about communication system and flow of communication. “Theories are crucial because they permit us to make our way through what may be a rather difficult thicket” (Littlejohn, p3).

I just want to make an article to speak about my city: Marseille.
Marseille was built about 600 before Christ on Mediterranean Sea coast by Greeks from Phocea. It is the oldest city in France. From this time to 21st century Marseille has been one of the most important harbors in France.
Marseille is currently the 2nd or 3rd city in France in terms of population depending on the chosen calculation (in city population or city + suburbs population).
